Download or read book Laboratory Soils Testing written by U.S. Army Corps of Engineers and published by Lulu.com. This book was released on 2007-12-28 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual presents recommended testing procedures for making determinations of the soil properties to be used in the design of civil works projects. It is not intended to be a text book on soils testing or to supplant the judgment of design engineers in specifying procedures to satisfy the requirements of a particular project, although it has been used in basic soil mechanics courses. Test procedures included are Water Content, Unit Weights, Void Ratio, Porosity and Degree Of Saturation, Liquid and Plastic Limits, Shrinkage Limit Test, Grain-size Analysis, Compaction Tests, Permeability Tests, Consolidation Test, Swell and Swell Pressure Tests. Drained Direct Shear Test, Triaxial Compression Tests, Determination of Critical Void Ratio, Unconfined Compression Test, Modified Providence Vibrated Density Test, and Pinhole Erosion Test for Identification of Dispersive Clays.
Download or read book The Recovery of Soils After Compaction A Laboratory Investigation Into the Effect of Wet dry Cycles on Bulk Density and Soil Hydraulic Functions written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Van den Akker et al. (2003) stated that "European subsoils are more threatened than ever in history" in an editorial referring to the results of the European Union concerted action "Experiences with the impact of subsoil compaction on soil crop growth and environment and ways to prevent subsoil compaction". Compaction of agricultural soils not only reduces yields but can lead to pollution of surface waters and the release of greenhouse gases. Understanding, therefore, how, and to what extent, subsoil compaction may be reversed seems of vital importance. The literature suggests that soils with a range of textures could recover structural properties such as total and macro-porosity, infiltration rate and stability, although the extent and depth of these changes varies greatly. Factors affecting the extent and depth of changes are the rate of wetting and drying and the matric potentials achieved during drying (influenced by crop cover and irrigation practices as well as climate), organic matter content and tillage history. There is, however, a limited amount of information regarding changes to the pore-size distribution and unsaturated hydraulic conductivity of soils with wet/dry cycles. Although there are models able to predict the compaction that would occur for a given set of conditions, as well as the compactibility of soils and surface crack generation, there are no predictive models that describe structural changes due to wet/dry cycles. The aims of this study were to assess the changes in bulk density and hydrological parameters of a range of soils, of varying texture and other physical and chemical properties, with wet/dry cycles and to explore the relationships between any measured changes and the measured soil properties. A series of laboratory experiments were designed to measure changes to the total porosity and pore size distribution and hydraulic functions of soil samples. Changes to bulk density and moisture content of undisturbed soil cores at field cap.

Available in PDF, EPUB and Kindle. Book excerpt: This Book Highlights The Procedures For 30 Tests Used To Measure The Engineering Properties Of Soil In Both Laboratory And Field Including Dynamic Testing Of Soils. All The Test Procedures Are Based On Indian Standard Practice And Are Very Close To Astm Standards. Features Of This Book Include: * Test Procedures And Tabular Forms For A Maximum Number Of Field And Laboratory Tests. * Classification Of The Soil Tests Based On Type Of Project And Type Of Soil. * A Set Of Questions Is Presented At The End Of Each Chapter For Self Examination. * For Each Test, Theoretical Principles And The Precautions To Be Followed During The Test Are Explained.This Book Will Be Useful To B.Tech./B.E. (Civil Engineering) And M.E./ M.Tech. (Geotechnical Engineering) Students As Laboratory Manual And Reference Book. It Is Hoped That This Book Will Also Be Useful To Field Engineers As Handbook In Soil Mechanics As It Helps In Deciding The Test Programme For A Given Project. Similarly, The Book Will Be Helpful For Quality Control Engineers.
